A Unified Political Command, also translated as Joint Political Command or Unified Political Leadership, was agreed in 1964 between the presidents of Egypt and Iraq as well as between the presidents of Egypt and North Yemen. Both projects were parallel but not linked with each other. The Unified Political Command was meant as a kind of transitional government which should prepare the gradual merger of Iraq with Egypt and North Yemen with Egypt in a new United Arab Republic.
Egypt and Iraq
Therefore, on 26 May 1964 Nasser and Arif agreed to form a joint Presidential Council and a Unified Political Command on 16 October 1964. This Unified Command was established on 20 December 1964 and did include the prime ministers of Egypt and Iraq as well as the ministers of economical and financial affairs and social planning of both sides and should act as a joint supreme instrument and highest executive authority to establish the economical, political and military unification of Egypt and Iraq within two years. The Iraqi Abd ar-Razzaq Muhyi ad-Din became General Secretary of the Unified Command. In July 1964 an Iraqi Arab Socialist Union was founded as political instrument to collect the support of the population and was formally united with the Egyptian Arab Socialist Union in September 1964. Also in September 1964 Egypt and Iraq agreed to unite their diplomatical corps and representations all over the world. In 1965 Iraq adopted the Egyptian coat of arms eagle and the Egyptian national anthem, declared Iraq as a democratic and socialist republic and announced a programme of nationalization. However, despite a few real meetings and sessions of this Unified Political Command the project stopped when the Nasserist prime minister of Iraq, Arif Abd ar-Razzaq, tried to overthrow president Arif in September 1965 and when Arif died in April 1966.
Egypt and Yemen
Parallelly, but not linked with the Egyptian-Iraqi merger project also between Nasser and as-Sallal a Unified Political Command was established on 13 July 1964. A joint government council of the Egyptian and Yemeni ministers should coordinate and integrate the Foreign, Defense, Economical, Social, Cultural and Information policy towards full unity. A Yemeni Arab Socialist Union was established already in 1964 and, in fact, Egyptian generals and officers took over the command of the republican forces in Yemen during the North Yemen Civil War. This civil war, however, prevented any progress and when Egypt withdraw its troops from Yemen after the Six-Day War as-Sallal was overthrown in November 1967 and also this project definitively ended.
Others
Similar Unified Political Commands and Joint Supreme Committees were planned and formed
within the Egyptian-Libyan-Syrian Federation of Arab Republics between Egypt, Libya and Sudan in April 1970. Later Syria joined instead of Sudan, but Egypt and Libya agreed to let a Unified Political Command prepare a more substantial union within the federation. The Egyptian-Libyan merger failed 1973 but on 21 December 1976 and in February 1977 the Syrian president Assad and the Egyptian president Anwar Sadat agreed to form a new bilateral Unified Political Command and a Political Supreme Council. In March 1977 Sudan's president Gaafar Nimeiry joined that Unified Political Command and all three presidents announced to form a new Federation of Arab Republics which never was realized and finally collapsed in November 1977 with the begin of Egyptian-Israeli peace talks.
between Syria and Iraq in October 1978 when both sides agreed to improve their military and economical cooperation and even planned to form a Syrian-Iraqi Union. A Supreme Political Authority and later also a Joint Political Command was formed with Iraqi president Ahmed Hassan al-Bakr, Syrian president Assad and Iraqi vice president Saddam Hussein. The project failed when Saddam Hussein replaced al-Bakr in July 1979.
